Thanks for looking!
ETA: For: JJFern First of all, let me start by saying "Thank You" for your comment. In answer to your question, I use layout sketches mostly for inspiration. I try to only look at the base of the sketch (what's behind the picture spots). Then, I sort through the pictures I plan to use (chosen by the colors of the photos that would go with the papers I'm using or vice versa)by the ones I must use, the ones I could use and the ones I'll use only if I have to. I focus on the ones I must use. I always do a dry run first - meaning I lay it out before I adhere anything. This helps me determine how I arrange my cardstock and patterned paper to get the right look, and how I can lay out the photos. If I have some "dead" spaces that I can't fill with a journal or embellishments, then I move to the pictures I could use to fill the space. Hope that helps!
